3 Claims.

The object of my invention is to provide a new method for heating and/ormaintaining proper temperature levels of solutions or fluids used astherapeutic agents, stimulants, foods or tonics administeredsubcutaneously, intravenously through a needle or other device attachedto the end of a tube, or intrarectally or other organs of the bodythrough a rubber tube or any other kind of tube usually employed in theadminisi tration of such fluids, solutions or drugs.

I attain these and other objects of my invention by the meansillustrated in the accompanying drawings, in which Figure 1 is a viewpartly in side elevation and i5 partly in longitudinal section of a partof my invention;

Fig. 2 is an end elevation at the outlet end of the device;

Fig. 3 is an end elevation at the inlet end of {En the device;

Fig. 4 is a vertical section on line 4-4 of Fig. 1; Fig. 5 is adiagrammatic view of the electric circuit used;

Fig. 6 is a view, partly in elevation, partly in 3.". longitudinal andpartly with only a portion of the shell broken away to show the interiorcontruction of one form of my invention;

Fig. 7 is a transverse section on approximately line of Fig. 6; and :1",Fig. 8 is a diagrammatic view of the electric wiring for this form ofthe invention.

Like numerals designate like parts in each of the several views.

Referring to the drawings, l indicates any conl i provide plates 2 ofinsulation maiiigl tion as supports for heater coils 3. Mounted onplates 2 is a semi-cylindrical plate or shelf on which I mount a tube orother suitable container 1:") 5. Container 5 has a suitable end plate 6(which may be removable if desired) and the inlet tube I4. I provide asuitable thermostat and thermostatic casing for same designated 1 andmounted in an end plate 6 as shown in Fig. l. I also pro- 43 vide asuitable removable end closure plate 8 at the outlet end of thecontainer. I provide suitable encircling reinforcing plates 9 toreinforce the container 5 at the end portions thereof, as shown in Fig.l.

50 I provide an outlet tube I mounted n closure plate 8 and an inlettube l4 mounted in closure plate 8. Inlet tube M may be connected with afaucet or provided with a conventional valve not claimed as a part ofthis invention. 0n out- 55 let tube ill I provide a valve casing l i inwhich a valve I2 is mounted, having a threaded portion mounted in thethreaded seat at l3. This plate is held in place by the thumb screws 24of closure member 8, as shown in Fig. 2. Plate 8 is preferably slightlybevelled at 26 to a seat tightly in the end of tube 5. Referring to Fig.5 illustrating the electric circuit, the numeral 15 designates a currentwire from which the wire it leads to the heater coils 3 which in turnare electrically connected with the armature switch ll of the relay ill.I provide a wire l9 leading from member I! to the second current wire20. I provide a wire 2| from current wire 29 to the relay 3 and a wire22 from the relay If! to the thermostat l and a wire 23 from thethermostat 1 to the current wire l8.

As will be understood by referring to Fig. 5 the thermostat may beadjusted to make and break the electric current at the particulartemperature desired and thereby control the operation of the relay 1 8to operate the armature or switch I! and thus connect or dis-connect theelectric coils from the electric switch and thereby control theiroperation and thereby automatically regulate the operation of the heater25 coils and thus the temperature of the liquid within the container 5.The heater coils may be of any desired length and position to secure auniform temperature of the fluid throughout the tube; or at the inletend; or at the outlet end as desired.

For successful use of an instrument of this character it is necessary(a) that solutions must be sterile and kept sterile; (b) that thesolutions should be heated to the proper temperature (apnin n iiiiii n.n innn the blood stream or under the skin at tha temperature; and (c)that the apparatus for heating solutions, i. e., the containers, shouldbe detachable for sterilizing.

By actual tests solutions flowing through tubes in small quantities andat a slow rate lose approximately 2 degrees for each inch of tubethrough which the solution flows. My apparatus not only heats thesolution to a predetermined temperature but delivers it at thistemperature into the vein by means of the attachment represented in Fig.6. This has been proven by placing a thermometer in the flow pipe nearthe needle where it can be observed. 0

As will be understood by referring to Fig. 2 of the drawings, theenclosure plate 8 may readily be removed by removing the thumb screws 24or disengaging the slotted ears 25 from said thumb screws 24.

using ordinary salt, sodium chloride, it is preferred to use thephosphorus pentoxide in the glazing of those wares which are diflicult,or practically impossible to glaze, by the use of ordinary salt, such aswares which have a high lime or high alumina content. Such wares may beglazed by the use of phosphorus pentoxide alone or after a preliminarysalt glaze produced in the usual manner. In some instances thephosphorus pentoxide glazing may be followed by a final salt glazing.

The gaseous mixture containing phosphorus pentoxide and suitable forglazing with the material may be obtained by any convenient means, suchas, by the partial or total oxidation 01 phosphate reduction furnacegas, by the oxidation of elemental phosphorus 'or by the volatilizationof phosphorus pentoxide. The amount of the phosphorus pentoxide requiredwill depend upon the composition and the surface or the were to beglazed. The operation of a 30 foot down-draft sewer pipe kiln givenbelow will serve to further indicate the method of operation a and theamounts of glazing materials required. One round of salt means to lbs.of sodium chloride, distributed equally to each fire box and oneround ofphosphorus pentoxide means 25 to 100 lbs. of phosphorus pentoxide, orits equivalent, distributed equally to each fire box. The ware to beglazed is placed in the kiln, brought to the proper temperature for saltglazing and contacted with a gaseous mixture containing the activeglazing agent in any one of the sequences outlined as follows:

1. One or more rounds o! phosphorus pentoxide.

2. One or more rounds of phosphorus pentoxide, and one or more rounds ofsodium chloride.

3. One or more rounds of sodium chloride, and one or more rounds ofphosphorus pentoxide.

4. One or more rounds oi sodium chloride, one or more rounds ofphosphorus pentoxide and one or more rounds of sodium chloride.

The kiln is operated throughout in substantially the same mannercurrently used in the salt glazing operation and after the final glazingoperation the kiln is cooled in the usual manner.

It will be seen, therefore, that this invention actually may be carriedout by the modification of certain details without departing from itsspirit or scope.

I claim:

1. Process for making glazed ceramic ware,

which comprises, burning a phosphate reduction furnace gas to form agaseous mixture containing phosphorus pentoxide, and contacting a glazedceramic ware with the gaseous mixture containing phosphorus pentoxide,while maintaining the ware at a glazing temperature.

2. Process for making glazed ceramic ware, which comprises, burningelemental phosphorus to form a gaseous mixture containing phosphoruspentoxide, and contacting an unglazed ceramic were with the gaseousmixture containing phosphorus pentoxide, while maintaining the were at aglazing temperature.

3. Process for making glazed ceramic ware, which comprises, contactingan unglazed ceramic ware with a gaseous mixture containing sodiumchloride, while maintaining the ware at a,

glazing temperature; and contacting the salt glazed ceramic were with agaseous mixture containing phosphorus pentoxide, while maintaining thewere at a glazing temperature.

4. Process for making glazed ceramic ware,

5. Process for making glazed ceramic ware,

which comprises, contacting a glazed ceramic ware with a gaseous mixturecontaining phosphorus pentoxide, while maintaining the ware at a glazingtemperature.

6. Process for making glazed ceramic ware, which comprises, contacting aceramic ware with a gaseous mixture containing phosphorus pentoxide,while maintaining the ware at a glazing temperature.
